Updated poppler packages fix multiple vulnerabilities

Description

Updated poppler packages fix security vulnerabilities:
Poppler is found to be affected by a stack based buffer overflow vulnerability
in the pdfseparate utility. Successfully exploiting this issue could allow
remote attackers to execute arbitrary code in the context of the affected
application. Failed exploits may result in denial-of-service conditions
(CVE-2013-4473).
Poppler was found to have a user controlled format string vulnerability because
it fails to sanitize user-supplied input. An attacker may exploit this issue to
execute arbitrary code in the context of the vulnerable application. Failed
exploit attempts will likely result in a denial-of-service condition
(CVE-2013-4474).
